Yukosteel did it again: he disassembled yet another lens.
This time the victim is the Voigtländer NOKTON 35mm f/0.9 and you can read the full article as well as see the images here.
In his conclusions he writes:
I’m not surprised to see that Voigtlander 35mm F0.9 Nokton Aspherical lens has very advanced build with extremely high machining quality of all parts. It is quite complex lens optically and mechanically and its proper maintenance and even basic cleaning requires highly skilled actions.
I would not recommend to perform any DIY cleaning and repair even if you have good experience working with lenses – it’s one of that more rare cases when I’d personally ship the lens to service center instead of attempting to repair it myself.
The build is very robust and solid, lots of large durable bolts are used to hold precisely machined parts together, and inner frame is all crafted from thick metal. Lots of brass is used for helicoid guiders including FLE mechanics, and aperture transmission is beautifully crafted too.
Personally I think the weakest spot of this lens is its electronics which may get potentially damaged or broken over decades of intense use, but that will not affect mechanical and optical performance of Voigtlander Nokton 35mm F0.9 in any way, so in general it’s very reliable tool that can serve for generations if properly maintained.
